2. type in "whereis gnuradio" -> if you found any remaining GNU Radio files, remove them.1. remove GNU Radio installations again (using apt).Dear Ruediger:It could be somewhat tedious, but could you try this?3. type in "whereis gnuradio-companion" -> if you found any remaining GNU Radio files, remove them.4. Search paths in PATH, PYTHONPATH, LD_LIBRARY_PATH, C_INCLUDE_PATH, CPLUS_INCLUDE_PATH and make sure that no GNU Radio libraries are still surviving (Or maybe you can use search the whole drive instead).5. reboot.6. re-install GNU Radio.7. Try running gnuradio-companion. Give an another reboot if it still does not work.

I went to the build directory generated by the build-gnuradio script and uninstalled using "make uninstall". I then used apt-get uninstall gnuradio to remove the package installed with apt-get. As a final step I reinstalled with apt-get install. Unfortunately gnuradio-companion is now not starting at all anymore throwing a memory access error.

Dear Ruediger:
Could you try removing all GNU Radio installations except one (that you would use), reboot the system, and then re-build -> re-execute the code? Because I have seen a case where multiple installations of GNU Radio messed up the PATH variable and caused a similar issue..

Dear Marcus and Kyeong Su Shin
indeed I used the build-gnuradio script before I installed gnuradio by apt-get. Sorry for not having mentioned that and in fact I did not deinstall after build-gnuradio.
Thank you,
Ruedi

Hm, ok, I was hoping for some parser problems within GRC to produce errorneous configuration of your QT GUI Frequency sink, but nooope. Exactly, byte-wise, the same file as mine.
Soooo, there's something crashing in Qt GUI.
So, how did you get 3.7.11.1 on Ubuntu 14.04? you say apt-get, but Canonical's repos only carry 3.7.2 for 14.04; since this might really be a binary compatibility problem, this is my main focus.
Cheers,
Marcus

Hello,
I'm using gnuradio-companion 3.7.11.1 installed using apt-get on Ubuntu 14.04.5 LTS running on a Lenovo T60.
The dialtone example works fine but once I'm using the frequency sink like e.g. in the resampler_demo.grc I get the following Runtime Error:
Generating: '/tmp/resampler_demo.py'
Executing: /usr/bin/python2 -u /tmp/resampler_demo.py

return _qtgui_swig.freq_sink_c_make(*args, **kwargs)
RuntimeError: std::exception
Any ideas?
Best wishes,
Ruedi
